ask me ask ME

í have been dying to ask this question for ages..do i have the "i have a GREAT sense of direction" face? people seem to lurvve asking me for directions when i am a "lost" person..within 10 min today, 2 people ask me which train to take to commonwealth/little india..though i was blasting my mp3 and had on my "ever-unfriendly" face..why..why..why? lucky for them i pointed in the right direction..
